UNITED STATES PATENT QFFICEQ JULIAN F. BIGELOW, OF WORCESTER,MASSACHUSETTS.

WIRE BRUSH.

SPECIFICATION forming part of Letters Patent No. 532,259, dated January8, 1895. Application filed September 28, 1894. $erial No. 524,361 (Nomodel.)

To all whom it may concern:

Be it known that I, JULIAN F. BIGELO'W, of WVorcester, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in l/Vire Brushes, of which the following is aspecification.

This invention relates to a brush composed of fine wire bristlesattached to a suitable handle and adapted particularly for use inkilling insects.

The invention has for its object to provide an improved construction ofa brush of this class whereby its wire bristles may be readily andsecurely attached to the handle and held in a series-of separated tuftswhich will permit the brush to pass quickly through the air for thepurpose of striking insects without displacing the air before itsufficiently to blow the insects away.

The invention consists in the improved construction which I will nowproceed to describe and claim.

Of the accompanying drawings, forming a part of thisspecification,-Figure 1 represents a side view of a wire brushconstructed in accordance with my invention. Fig. 2 represents a sectionon line 22 of Fig. 1. Fig. 3 represents a section on line 3-3 of Fig. 1.Fig. 4. represents a section on line 44 of Fig. 1.

The same letters and numerals of reference indicate the same parts inall the figures.

In carrying out my invention, I take a series of fine wires, preferablyof steel, and form the sameinto a bunch,the members or strands of whichare parallel, and then bend the bunch at the middle of its length,thus'forming a neck 2 and twoparallel bunches 5 5 of wires connected bythe neck. I then insert the neck 2 and bunches 5 5 in a sheet metalferrule a which is suitably secured to one end of a handle I). Theferrule is of sufficient length to receive the neck 2 and a considerablelength of the wires composing the bunches 5 5, and is engaged with theneck and bunches by being compressed thereon, the sides of the ferruleat opposite points being pressed inwardlyIto cause them: to bear closelyupon the surfaces of the bunches 5 5. I prefer in compressing theferrule, to form indentations a. a therein, said indentations enteringthe depressions between the bunches 5 5 and terminating at the neck 2,so that the lower ends of said indentations form shoulders bearing uponthe neck, thus efiectually preventing the removal of the wires from theferrule, such removal being additionally prevented by the compression orcrowding together of the wires caused by the compression of the ferrule.

The portions of the wires that project from the ferrule constituteflexible bristles 6 which are arranged in separated tufts, as shown inFigs. 1 and 2, by means of a ligature 0 composed of a cord or wire orother flexible device, whichis interwoven with the tufts of bristles insuch manner as to separate them in the manner shown and form air spacesbetween the tufts, the bristles being thus caused to diverge and form afan-shaped brush composed of a flat series or row of separated tufts, sothat when the brush is impelled through the air in the act of strikingan insect on a wall or other surface, the air will not be forced aheadof the brush sufficiently to drive away the insect, but will passthrough the brush freely, thus decreasing the liability of the escape ofths insect.

' I claim- A brush composed of a series of bentwires comprising theneck-portion 2, the parallel bunches 5 5 composed of strands extendingfrom the neck, and the diverging bristles 6 constituting continuationsof said strands; a ligature holding said bristles in a fiat series ofseparated tufts; an operating handle; and aferrule which receives and iscompressed upon the neck and bunches 5.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 20th day of September, A. D.1894..

JULIAN F. BIGELOW.
